B noting SAM is built over CloudFormation.

B - Canary Deployment

B IS HIGHLY CORRECT

B is the correct answer This is a Legit dumps I passed my Exam on June 15th, 2023 with a 870 score. I studied both DOP-C01 and DOP-C02, 95% of the questions came from them. Most questions came from DOP-C01 with 80% and DOP-C02 with 15%. Get contributor access to read all comments and maybe access other exams if you plan to take more exams. Go through the questions at least twice or more to get familiar with it!

anyone took the exam lately? is this still valid or should I go ahead with C02?

B - Canary Deployment

B- Canary deployment of Lambda is done using AWS SAM that comes built in with CodeDeploy. https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/automating-updates-to-serverless-apps.html

Canary Deployment is the use case for this scenario while the other two are Blue green deployment. Option A is using Route53 failover which is not necessary for the scenario.

New as of September 6th, 2022 NO.265 A company updated the AWS CloudFormation template tor a critical business application. The stack update process Tailed due to an error in me updated template, and CloudFormation automatically began the stack rollback process Later, a DevOps engineer found the application was still unavailable, and that the stack was in the UPDATE_ROLLBACK_FALED state Which combination of actions will allow the stack rollback to complete successful/? (Select 2) A. Attach the AWSCloudFormationFulAccess IAM policy to the CloudFormation role B. Automatically heal the stack resources using CloudFormation drift detection. C. Issue a ContinueUpdateRolback command from the CloudFormation console or AWS CLI D. Manually the resources to match the expectations of the stack. E.

New as of September 6th, 2022 A company's application is running on Amazon EC2 instances in an Auto Scaling group. A DevOps engineer needs to ensure there are at least four application servers running at all times. Whenever an update has to be made to the application, the engineer creates a new AMI with the updated configuration and updates the AWS CloudFormation template with the new AMI ID. After the stack update finishes, the engineer manually terminates the old instances one by one. verifying that the new instance is operational before proceeding. The engineer needs to automate this process. Which action will allow for the LEAST number of manual steps moving forward? A. Update the CloudFormation template to include the UpdatePolicy attribute with the AutoScalingRollingUpdate policy. B. Update the CloudFormation template to include the UpdatePolicy attribute with the AutoScalingReplacingUpdate policy.

New as of September 6th, 2022 A company needs to implement a robust CI/CD pipeline to automate the deployment of an application in AWS. The pipeline must support continuous integration, continuous delivery, and automatic rollback upon deployment failure. The entire CI/CD pipeline must be capable of being re- provisioned in alternate AWS accounts or Regions within minutes. A DevOps engineer has already created an AWS CodeCommit repository to store the source code. Which combination of actions should be taken when building this pipeline to meet these requirements? (Select THREE.) A. Configure an AWS CodePipehne pipeline with a build stage using AWS CodeBuild. B. Copy the build artifact from CodeCommit to Amazon S3. C. Create an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB) and set the ALB as the deployment target in AWS CodePipeline. D. Create an AWS Elastic Beanstalk environment as the deployment target in AWS CodePipeline. E. Implement an Amazon SQS queue to decouple the pipeline components. F. Provision all resources using AWS CloudFormation.

New as of September 6th, 2022 A company runs several applications across multiple AWS accounts in an organization in AWS Organizations. Some of the resources are not tagged properly, and the company's finance team cannot determine which costs are associated with which applications. A DevOps engineer must remediate this issue and prevent this issue from happening in the future. Which combination of actions should the DevOps engineer take to meet these requirements? (Select TWO.) A. Activate the user-defined cost allocation tags in each AWS account. B. Create and attach an SCP that requires a specific tag. C. Define each line of business (LOB) in AWS Budgets. Assign the required tag to each resource. D. Scan all accounts with Tag Editor. Assign the required tag to each resource. E. Use the budget report to find untagged resources. Assign the required tag to each resource.

New as of September 6th, 2022 A company is using AWS Organizations and wants to implement a governance strategy with the following requirements: - AWS resource access is restricted to the same two Regions for all accounts. - AWS services are limited to a specific group of authorized services for all accounts. - Authentication is provided by Active Directory. - Access permissions are organized by job function and are identical in each account. Which solution will meet these requirements? A. Establish an organizational unit (OU) with group policies in the master account to restrict Regions and authorized services. Use AWS Cloud Formation StackSets to provision roles with permissions for each job function, including an IAM trust policy for IAM identity provider authentication in each account.

NEw Q as of September 6th, 2022 A DevOps engineer is currently running a container-based workload on-premises The engineer wants to move the application to AWS, but needs to keep the on-premises solution active because not all APIs will move at the same time. The traffic between AWS and the on-premises network should be secure and encrypted at all times. Low management overload is also a requirement. Which combination of actions will meet these criteria? (Select THREE.) Create a Network Load Balancer and. for each service, create a listener that points to the correct set of containers either in AWS or on-premises. Create an Application Load Balancer and, for each service, create a listener that points to the correct set of containers either in AWS or on-premises.

B make sense
